购销广告中的数学学问

本文通过对需求市场的分析，得出人们的潜在购买量随广告费的增加而增大。但实际需求量是随机的。为使问题简化，并做出定量分析，本文假定实际需求量服从均匀分布，并用数学方法确定广告费和购进量的最优值。

Mathematical Knowledge for Buying and Selling Adertisement

Through the market analysis for demand and requirement,the paper has come to the conclusion that the potential buying capability of the masses will become bigger along with the cost of advertisement,but in reality the practical amount is at random,and in order to simplify the problem and make out a quantity analysis,suppose the practical amount will submit to an even distribuction,i.e.define advertisement by mathematic approach,which is the maximum for the amount of buying.
